The 'z-primary object 'of the invention is the provision "ofamachine ofthls character,

' T wherein "the filtering elements are arranged p "the inner faces'of QPPOSBdfGIld. walls 10, of this reservoir are cleats 11, forsupporting in a rotor,'which revolves at anextremely low-rate of speed', so as to perm-it'theiwater Ito p'ercolat'e through" the ifi-ltering'elements" V "heightin the reservoir to regulate ,main- "taina predetermined water levelwithin the v latter. Opening throughthe :side wall .13, I adjacentfto the dam-boards .12, is a clean- 1- to :remove all foreign matter from-the water,

the clean water being let oil at one endiof the machine, .while the foreign matter from the filtering elements is discharged from the other end-of said machine.

Another object of the invention s the provision of a machine of this character, Wherein the construction thereof is novel 111 form."

and inthe construction and arrangement of parts the filtering elements will be thor- [oughly cleaned to render the machine sanitary and operative atialltimes.

' A further object. of he'inventionis the provision of a machine'of vthis character, wherein the filtering elements are continuously washed to remove all foreign'matter therefrom, and the dirty'water is discharged 1 therefrom during the operation of said ma- -"chine. j J

' A still further object of v the invention is the provision of a machine of this character,

which is comparativelysimple in construetion, thoroughly reliable and efiicient I in operation, strong, durable,- and inexpensive in'manufacture and installation. 'lVith these and other objects in View the invention consists in the features of construc tion, combination and arrangement of parts] as will be hereinafter fully described, i llustrated in the accompanying drawings, and 4 pointed out in the claim hereunto appended.
